AI Technical Summary
Conventional electric power steering apparatuses face issues with erroneous abnormality detection during backup control, where the same threshold value used for normal conditions can lead to incorrect determination of abnormalities, causing unnecessary shutdowns or continued operation with faults.
The electric power steering apparatus introduces an abnormality control mode that adjusts the control amount and threshold values based on the specific abnormality detected, ensuring accurate determination of additional abnormalities and preventing erroneous shutdowns by dynamically changing the threshold values during backup control.
This approach allows for continued motor control with accurate abnormality detection, preventing erroneous determinations and ensuring safe operation by adapting control strategies based on the nature and location of sensor abnormalities.
